SPECIFICATION forming part of Letters Patent No. 533,695, dated February 5, 1895.

Application filed April 15,1893. Serial No. 470,493. (No model.)

To aZZ whom it may concern:

Be it known that I, GEORGE P. YOUMANS, a citizen of the United States, residing at the village of Galesburg, in the county of Kalamazoo and State of Michigan, have invented certain new and useful Improvements in Windmills, of which the following is a specification.

My invention relates to windmills and more particularly to the class of windmills used for pumping and for similar purposes.

The objects of my invention are, first, to provide a windmill gear that shall lift the pump piston with great power and let it down quickly; second, to provide a windmill gear that is incased and so protected from the corroding effects of the elements; third, to provide a wind mill that shall run evenly without constant vibration of the vane and other parts and so prevent useless wear; fourth, to provide a windmill with an automatic brake that comes into action as soon as the wheel is turned from the wind by the vane; fifth, to lessen the weight of material required in a windmill of a given power; sixth, to simplify the construction of a geared windmill. I accomplish these objects by the mechanism shown in the accompanying drawings, in which- Figure 1, is a top view of my improved wind-mill the wind wheel and vane not being shown. Fig. 2, is a side view of the same, in gear, the wheel shaft pointing to the left. Fig. 3, is a side view partly in section on line 3-3 of Fig. 2. Fig. 4c, is a sectional view on line 4-4 of Fig. 2, looking in the direction of the arrows. Fig. 5, is a view of the face of wheel G. Figs. 6 and 7 are views of pinion I.

Similar letters of reference refer to similar parts throughout the several views.

The frame A, to which all the remaining parts are attached is cast in one piece and rests on a turntable on the top of a tower. Neither the wind wheel or the vane is shown in the drawings for the form of neither is material to my invention. The wind-wheel is attached to shaft B. The pinion I is also firmly fixed on shaft B. The pinion I meshes with gear wheel 0, which is fixed on shaft G. On the back of gear wheel 0 is a wrist to which the pitman E is journaled. The pitman E,

projects upwardly and is jourualed to a pin at the top of the pump rod F. Across the frame of the vane D is a curved bar D adapted to act as a brake on wheel 0 when the mill is turned from the wind.

The mill is thrown into and out of gear by means of the chain c which passes up by the pump rod F at the center of the turn table and out over suitable sheave guides in the usual manner and attaches to the vane D.

The rod II is pivoted to the frame A atf. The rod H passes through an eyelet b on the vane D. On the rod H is the coiled spring 0. adapted to press against the eyelet h and tends to carry the vane out beyond a point at right angles to the wind wheel. A short spring a is on the rod H near its end beyond eyelet b and serves to cushion the vane D when the mill is put into gear. Nuts a and c are to ad just the small springs on the rod to effect this purpose.

Vane D should be thrown beyond a right angle because it is pivoted to the frame A to one side of the center line of the shaftof the wind wheel, and the center of the turntable is between the line of the wind-wheel shaft and the pivoting of the vane, thus making it necessary in order to balance the vane and the wind wheel and so bring the wheel square to the wind in starting. When the wind increases and the pressure on the wheel becomes greater than is required for the work to be done the wind wheel and vane close together compressing spring a on rod H, so that the wind wheel stands at an oblique angle to the wind and so lessens the force exerted on the wheel.

The pinion I and the gear wheel 0 are constructed and mesh together in such a manner that on the upward stroke the motion is slow and powerful and on the downward stroke the motion is rapid. There are four lines of cogs and notches on each wheel adapted to mesh with each other successively. On the upward stroke the row of cogs h of pinion I meshes with the row of cogs h of gear C. When the end of row h is reached a tooth of row g of pinion I meshes into row 9' of gear 0. Then rowsi and z" mesh and then j and j which gives a quick movement. When the end of row 9" is reached then rows iand t" mesh, then g and 9, then It and it again which carries the wheel once'around. Examination will show that as the size of each section of the pinion I is the same and as it meshes with gear 0 at varying distances from the center with cogs all of the size it gives a varying speed to the gear wheel 0. As here shown and applied the motion up is slow and powerful to raise the pump rod and piston,

10 and lets it down rapidly when there is little or no Work to be performed. The cogs in the circles g and t" serve principally as guides in shifting the action of the gear I and G from rows h to j, andalso prevent an abrupt change I 5 in the motion.

, The frame A is cast in such a form that it entirely incases the gearing of wheels I and C, a circular portion extending over the surface of the wheel 0 just inside of the rim 0.

The rim 0 is broad to afford a good surface for the action of the brake D.

I have shown the vane D pivoted toone side of the center line of the wind wheel as I prefer to have it in that position; because the '2 5 mill responds more quickly to the action of the wind when thrown into or out of gear.

\Vhen the vane D is thrown round so that brake D presses the rim 0 of gear wheel 0,

I prefer to'have the plane of the vane D at 0 an acute angle to the plane of the wind wheel as that causes it to remain more steadily in the wind.

It will be noticed on examiningmy invention that the pitman E which is attached to 3 5 the gear wheel 0 oscillates in a vertical plane 1 The in line with the axis of the wind wheel.

object of so placing the pitman is to prevent a vibratory motion which would be caused if the pitman oscillated from side to side of the 40 line of the axis.

Many variations in construction will readily of cogs on the gearing is not material to my. invention so long as the power and speed is varied by shifting the action to and from the center of the main wheel. It is not material that the exact form of the frame be preserved or that it be cast in one piece. The form makes it convenient to do so.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is 1. In a wind mill, the combination of the frame, A, the shaft, B, bearing the wind wheel; the gear, I, with separate and distinct rows of cogs thereon; a gear wheel, 0, with cogs thereon; at varying distances from the center of said gear adapted to mesh successively with the rows of cogs on the gear, I; the gear, 0, being connected by suitable means to a pump rod so that the pump rod shall be actuated slowly and powerfully on the up stroke and will. be compelled to descend quickly, forthe purpose specified.

2. In a wind mill, the combination of a pinion having rows of cogs along its length; and a gear wheel with rows of cogs at varying distances from its center, the cogs on said pinion and gear wheel being adapted to mesh with each other successively, for the purpose specified.

3. In a wind mill, the combination of the frame, A, adapted to incase the gearing of the gear wheels; a pinion, I, with rows of cogs along its length driven by the wind wheel;

. able means to the pump rod, for the purpose specified.

, 4. In a wind mill, the combination of the shaft, B,bearinga wind wheel; the pinion, I; 'the gear, 0; the pitman, E; the pump rod, F, in a suitable guide; the incasing frame, A, resting on a suitable turntable; thevane, D, bearing brake, D; the operating chain, c, passingup through the center of the turn table and out over suitable guides to deflect the vane, D; the rod, H, pivoted to frame, A, as at f, and passing through eyelet, h; and the springs, a and a, substantially as described for the purpose specified.

5. In a wind mill, the combination with the frame and vane or rod, H, pivoted to the frame and passing through eyelet, b, on the vane; and the adjustable springs, a and a, on each side of the eyelet adapted to control the angle of the vane to the wind wheel for the purpose of governing the mill, substantially as described. a A

6. In a wind mill, the combination with the wind wheel; the vane pivoted to the frame to one side of the center of the wind wheel shaft and adapted, when thrown into the wind, to open from the center of the shaft to an angle greater than a right-angle to the plane of the wind wheel so that a light breeze will swing the wheel square to the wind and a heavy breeze will close the vane toward the wheel so that the wheel will not receive the full force of the wind; to regulate the wheel to secure the best effects from a light breeze and regulate its speed in a heavy wind, for the purpose specified.

In witness whereof I have hereunto set my hand and seal in the presence of two wit- 'nesses.
